Javax ImageIO IIOException for apparently no reason

Question

Hey all, I have a Java problem. For my senior research class, I\'m pretty much finished but I just have to analyze some data in images I generated. I don\'t want to tag this as

Answer 1

In the problematic line, shouldn't it been actualFiles[i] instead of expectedFiles[i]?

Answer 2

new File("C:\\Users\\Rowe\\workspace\\Senior Research\\testExpect"+expectedFiles[i])

Let's shorten the directory to C:\\yourDir. Your code will be yielding paths like

C:\\yourDirexpectedFiles1.bmp

Not what you want:

C:\\yourDir\\expectedFiles1.bmp

You forgot the path separator.

It is much better to use the two-File-arg constructor to File:

File actualImageFile = new File(actualDir, expectedFiles[i]);
actualImage = ImageIO.read(actualImageFile);

Hope that helps!
